¼ in (3.5 mm) TRS headphone jack
Obviously there's a typo in there, but surely it's 1/4in and not 3.5mm?
Why 8x fixed gain? That seems awfully high for something non-portable that is likely to be used with mains powered 2v sources.
And maybe you shouldn't have told everyone that the XLR output is just for the convenience of those with XLR cables. At least not until after all the balanced fanboys had been boasting about how much better the amp sounded in 'balanced' mode for a few months :) Just add a bit more gain to the XLR output and they wouldn't have been any the wiser!

Hey Jaggi,
Thanks for catching that...I'll work on getting the 3.5mm fixed.
As for the XLR jack, there have been some observations of the 4-pin sounding a bit better than the 1/4" output. One thought with this amp was that the separation of ground between right and left channels might have an effect. Will be interesting to see how many people notice a difference. We prefer XLR and you'll see us try to make that available whenever we can.

Glad to have it confirmed that it's a 1/4 inch socket, the first time I read the specs I only registered the 3.5mm and nearly threw rotten fruit at the screen :)
And I'm actually quite happy that you chose to add the 4-pin XLR output, if for no other reason than that it will help to consolidate 4-pin XLR as the standard connector for balanced headphone cables. In theory at least I do like the lack of shorting you get with XLR and I understand it has other technical benefits over phono plugs.
